In today’s world, convenience and security are both very important for every home. Many Singapore homeowners are now switching from traditional keys to digital locks. Digital locks are not only modern and stylish, but they also make life easier — no more worries about losing keys or forgetting to lock the door.
If you already have a door in your HDB flat, condo, or landed home, the good news is that you don’t need to replace it completely. Add a digital lock to your current door with ease. In this guide, we’ll walk you through what you need to know before installation, the steps involved, and some useful tips.
Why Choose a Digital Door Lock?
- Keyless entry – Eliminate the need to carry, lose, or duplicate physical keys by using PIN codes, fingerprints, or smartphones to unlock your door.
- Multiple access options – Use a PIN code, fingerprint, Facial Recognition, RFID cards, or even your phone to unlock.
- Better security – Many digital locks come with features like auto-locking and alarms.
- Modern look – A sleek digital lock instantly upgrades the appearance of your door.
- Convenience for families – Everyone can have their own code or fingerprint, so no more spare keys needed.
- Enhanced Security Features – They often come with tamper alarms and auto-lock functions that engage when the door closes, providing increased protection against unauthorized entry.
- Remote Access and Control – Many smart locks connect to your Wi-Fi, allowing you to lock or unlock your door from your smartphone, no matter where you are.
Can You Upgrade Your Current Door with a Digital Lock?
Most existing doors in Singapore can support a digital lock, but there are a few things to check first:
- Door thickness – Standard locks are suitable for doors 35mm–70mm thick.
- Door material – Wooden and laminate doors are generally suitable, but the material must be strong enough to support the lock.
- Existing holes – If your door already has a handle or deadbolt, the digital lock may use the same spot.
- Fire–Rated–Door – If your door is fire-rated, ensure the digital lock you choose is certified to meet relevant fire safety regulations.
- Existing Door Condition: The door should be in good condition, with no existing issues that could hinder the installation process.
Steps to Install a Digital Lock on Your Door
When you hire a professional installer in Singapore, the process is smooth and stress-free. Here’s what usually happens during installation:
1. Site Inspection
The installer will first check your existing door and frame. They’ll confirm the thickness, alignment, and whether any extra adjustments are needed.
2. Removing the Old Lock
If your door already has a traditional handle or deadbolt, the installer will carefully remove it without damaging the surface.
3. Preparing the Door
The installer will measure and drill any new holes if required. This ensures the lock is fitted properly and works without issues.
4. Fitting the Digital Lock
The installer carefully aligns and fixes both the inside and outside parts of the lock. Professionals make sure the lock sits flush against the door for a polished look.
5. Power Setup
Most digital locks run on batteries. The installer will insert the batteries, check the wiring (if any), and confirm the lock powers up correctly.
6. Configuration and Testing
The installer will program the lock for you, including setting up the first PIN code, fingerprint registration, or mobile app connection. They will also test the lock multiple times to ensure it opens and locks smoothly.
7. User Guidance
Before leaving, the installer will guide you and your family members on how to use the lock. They’ll explain how to unlock, change codes, and what to do when the battery runs low.
Should You DIY or Hire a Professional?
While some people install digital locks themselves, hiring a professional installer in Singapore is highly recommended. Here’s why:

Yes, you can install a digital lock on most HDB or condo doors in Singapore. Check your door’s thickness (35–50mm), condition, and whether the existing lock hole fits the digital lock or requires new drilling. Professional installation is recommended for proper fitting.
While DIY installation is possible for some models, professional installation is recommended to ensure proper alignment, security, and warranty coverage.
Fire-rated digital lock must be installed on a fire-rated door to maintain its fire safety rating. Installing it on a normal door removes the fire protection benefits.
